Explanation
In
1912, the Krupp company in Essen patented a new material that
was known in the inter-war period as 'Nirosta' or 'V2a steel'.
It was soon adopted for applications ranging from the construction
of containers for the chemical industry and components for
motorcar and aviation design to building materials and domestic
appliances. Chromium-nickel
steel, material No. 1.4301 under DIN 17440 The generic term
stainless steel embraces over 100 separate rust and acid-resistant
steels.
We manufacture
our builders hardware utilizing a chromiumnickel steel classified
as material
1.4301 under DIN 17440. It contains approx. 18 % chromium
and 8 % nickel. This alloy has proved particularly successful
in the building industry.
Properties
of stainless steel
Stainless steel is an excellent material for door and window
furniture, since its surface is extremely resistant to corrosion,
knocks, scratches and abrasion and, owing to the chromium
and nickel additives, needs little looking after.
An invisible
passive layer forms on the surface that is even said to kill
bacteria.
Applications
We recommend stainless steel for all door and window furniture
subject to heavy use, viz.
in public buildings, office blocks, hospitals, motorway
service areas, and public parks, at sporting venues, or
on ships - wherever large numbers of people regularly congregate
and reliable, low-maintenance fittings are a must.
Care
Stainless steel furniture basically requires no looking
after. Smudges can be removed with a damp cloth. Outdoor
fittings and those at chlorinated pools can develop what
is known as 'flash rust' after a while. This is not generated
from within the metal itself and can be removed by vigorous
rubbing.
Notes
on selection
When selecting and ordering door and window furniture, please
read carefully the general material and technical data in
this Catalogue. This avoids misunderstandings, queries,
and delays.
